This invention relates to new and useful improvements in flying machines.

The invention has for an object the provision of a device of the class mentioned, 5 which is of simple durable construction, de-

sirable in use andeflicient in action and which may be manufactured and soldat a reasonable cost.

For further comprehension of theinvention, and of the objects and advantages thereof, reference will be had to the followingI description and accompanying drawings, and to the appended claims in which the various novel features of the invention are more particularly set forth.

In the accompanyingdrawing forming a material part of this disclosure l Fig. 1 is a front elevational viewv of a device constructed accordingto this invention.

Fig.'7 is a plan View of the device.V

The referenceA numeral 10 .indicates gener-v allya tunnel member havinga rear opening and a much larger front opening. A pilots chamber 11 is Vattached upon the tunnel memberand extends to the front thereof. This pilots chamber is of smaller width than the tunnel member so as to provide` air passages at the sides shown in.Fi`g. 1. A seat 12 is .arranged within the pilots chamber and a pilot 13 is shown occupying'the seat.

Main wings 14 are attached uponthe sides Vof the tunnel member.V Parallel spaced vertical wal'ls 15 connect with the rear portion of a tunnel member and extend materially to the rear. Thesewalls are reinforced by horizontal ribs 16. A horizontal tail wing 17 connects with the rear portion of theV walls 1.5.. The outerA tips 18 of the main wings are separate from the other portions and are hingedly connected as at 19. v

One of the hinged sections 18 connects with an upperwire 20 and with a lower wire 21, both wires leading to the pilots chamber and one of these wires being wound in one direction upon a drum 22 on a steering rod 23 op- L erable by the pilot, the other of the wires being wound upon the drum in the opposite direction to the first wire so that when the pilot turns the steering rod 23 in one direction the wing section 18 will be moved upwards and when the steering rod is turned in the opposite direction the section will be movedl downwards. j

The other hinged section 18 is similarly connected with wires 20 and 21 engaged upon a drum 22 mounted upon a steering rod 23 also operable by the pilot. This arrangement permits individual control of the sections 18 on the ends of the main wing. In plan view as seen in Fig. 7 the inner ends of the sections 18 are adjacent the outer ends of the main wing and the lines of contact are inclined from the front of the machine diverging towards the rea-r.

A curved passage 24 passes thru the tunnel member 10 and an adjustable top vane 25 vwith air channels 26 engages in the top of the curved passage. Within the passage, central andy bottom vanes 27 and 28,.respectively are stationarily mounted.. These vanes are proprovidedwith air channels 26.V The top vane 25 is fixed 'upon a shaft 29 provided with a `worm ywheel 30 meshingV with a worm pinion '.31 upon a Vshaft 32. The shaft 32 is rotatively mounted and extends within reach ofthe pilot. A hand wheel 33 is provided on the end of thisA shaft. The air channels 26 providelarge surfaces for passing currents of air to engage against andv stabilizepthe machine.

v. `A horizontal bottom propeller 34 is disposedwithin the bottom of the passage24 yand is mounted upon a shaftprovided with a pulley ,35. This pulley connects with a belt 36 connected with another pulley upon the :shaft of a motor 37. A vertical propeller 38 ismounted uponthe shaft ofthe said motor. The motor is disposedv within the tunnel 10 and 'the vertical propeller 38 lrotavtively enfV gages in the rear end of the tunnel. V

A landing gear wing 39 is pivotally mounted intermediate of its ends as at 40 upon a pair of brackets 41 depending from the tunnel member 10. Thesebrackets are provided with arcuate slots 42 engaged by pins 43 projecting from the wing 39. Front wheels 44 engage upon the front of the wing 39 and rear springs 45 upon the rear of the wing. These springs are firmly connected with vertical pegs 46. These pegs have slots 47 engaged by transverse shafts 48 supporting rear wheels 49. rihe wing 39 has an opening 5() permitting the peg 46 to move upwards if the springs 45 flex during landing.

A rack 51 is slidably mounted in the pilots chamber and connects with a spring 52 connected with the wing 39. The rack 51 meshes with a gear 53 on a shaft provided with a worm wheel 54. The worm wheel meshes with a worm pinion 55 upon a shaft 56 rotatively mounted and provided with a collar 57 having a plurality' of peripheral apertures. The shaft 56 is connected by bevel gears 58 to a steering rod 59 arranged in the vicinity of the pilot and provided with a steering wheel 60. A latch 61 is arranged to engage in the apertures of the collar 57 for latching the shaft 56 against rotation. The latch 61 is connected by a link 62 with a lever latch 63.

The tunnel member 10 is provided with side wings 64 fixed upon arbors 65 arranged for rotation. Sprocket wheels 66 are attached upon the arbors and connect with sprocket chains 67 engaging upon sprocket wheels 68. The sprocket wheels 68 are fixed upon shafts rotatively mounted and provided with gears 69. These gears mesh with smaller gears 70 connected with a handle 71 for manual rotation. A spring pawl 72 is arranged for latching the gear 70 against rotation. A top fin is provided upon the mainy wings 14 and consists of a rear section 73 and a front section 74. Dot and dash lines 75 in Fig. 1 represent elevated positions of the end sections 18 of the wings.

In operationof the device, engine 37 drives propeller 38 for urging the machine forwards.y The engine also drives propeller 34 and air currents set up by this propeller act against the top of the landing gear Wing 39.`

This wing may be angularly positioned as indicated by the dot and dash lines Vin Fig. 2 for directing the air current set up by the '1 propeller towards the front or towards the rear. It is pointed out that component forces Y are produced by these air currents so as to tend to move the machine.

-The pilot may move the lever catch 63 for disengaging the latch 61 and then manually turn hand wheels 60 for`adjusting the inclinationof the landing gear wing 39 to desirable inclinations. y He may also operate the steering rods 23 and`23 for operating the 3 main wing end sections 18.

The amount of air current set up by the propeller 34 may be controlled by manipulation of the hand wheel 33. This changes the inclination of the adjustable vane 25. change in inclination of the vane causes different amount of air to pass thru the air channels of this vane and the stationary vanes. IIandle 71 may be used for adjusting the position of the side wings 64. Adjusting of thesek wings changes the amount of air entering the tunnel member 10. A change in the supply of this air changes the working effect of the propeller 38.
